Abstract
Dosimetric Comparison of 3 Dimensional conformal Radiotherapy
(3DCRT) with Intensity Modulated Radiotherapy (IMRT) with
Volumetric –Modulated Arc Therapy (VMAT) for Breast cancer
The merit of this study was for Tan IMRT. The differences in patient populations,
dose prescription, target volume delineation and definition, and radiation procedures,
such as the number of fields and arcs employed in t-IMRT and t-VMAT, make it
challenging to compare the various kinds of research. This could account for the data
on HI, CI, MUs, and OAR sparing that is somewhat contradictory .
Because there were few differences between the methods 3DCRT and IMRT, we do
not believe that the slight advantage IMRT has in terms of CI and HI will have an
impact on clinical judgments. No heart problems or radiation pneumonitis have been
reported since the study’s inception. Additionally, it was discovered that IMRT
offered the best protection against high radiation doses. Moreover, IMRT significantly
reduces cardiac risk when compared to 3DCRT and VMAT. Thus, IMRT can be
considered a viable option if it is made available to carefully chosen breast patients .
These results show that tangential IMRT may not be the optimal technique for all
WBRT patients, and its application should be assessed based on the patient’s
anatomy. Because it takes less time for QC and is more comfortable for the patient,
who in this case has to spend less time in the machine during the treatment, it is
preferable to use the 3D CRT technique when planning treatment with a volume of
dose within the safe limits for the organs at risk. IMRT offers the highest protection
against the risk of cardiac and organs at risk for excessive radiation doses.
The major advantage of 3DCRT over IMRT is the shorter treatment time. The
findings of this study propose that IMRT be taken into consideration as a feasible
option for the treatment of various sites of tumors independent of tumor size and site
due to IMRT’s ability to develop highly conformal and efficient treatment plans that
are clinically comparable to 3D-CRT.
